Small update. I bought the Siberia V2's to test out and I must say I am not too impressed so far. I picked up the 3.5mm jack verrsion not realizing it was so until I picked it up (bought off kijiji). I plugged it in to my onboard sound and the sound on the headset is super quiet. I tried BF3 last night and it was also extremely quiet on full volume.

Is this a driver issue or is this because I am not using a dedicated sound card?

I use mine with onboard sound without issue. They will play louder than I like without distortion. Are you sure your volumes are all turned up in settings and in game/music programs. I leave the volume settings in windows loud and then use the volume on the headset to limit it. Try them in a phone/mp3 player if that doesn't work to ensure the headset is not busted.
